Popis:	A novel bis (dmit) complex of copper (II), [(C3H7)4N]2[Cu(dmit)2] (1), where dmit is 2-thioxo-1,3-dithiole-4,5-dithiolate, was prepared and structurally characterized by X-ray single crystal diffraction. The copper (II) atom is tetracoordinated by four dmit S atoms, forming a nearly square planar arrangement. The [Cu(dmit)2]2- anions and the [(C3H7)4N]+ counter-cations form a three-dimensional solid-state structure by C–H…S hydrogen bonds. The third-order nonlinear optical properties of the complex were determined by picosecond Z-scan technique at a wavelength of 1064 nm. The results indicate the compound exhibits reverse saturation absorption and self-defocusing performance. The molecular second-order hyperpolarizability γ is calculated to be as high as (1.8±0.2)×10-30 esu. (© 2007 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)
